Gurit is a leading manufacturer and supplier of epoxy gelcoat products.
Using the unique skills developed in epoxy formulation and cutting edge process capability, Gurit's gelcoat range has overcome many challenges facing composite manufacturers today, from the small automotive panel moulding, up to the wind turbine blade over 40 metres in length.
Understanding the intricate and demanding requirements placed on surfacing solutions has been fundamental to Gurit's novel, light-stable epoxy gelcoats for use in both prepreg and infused blades giving one of the following:
Fully performing light-stable external surface coat
Light-stable process coat, paintable with minimal surface preparation
With in-depth experience of this critical area of blade manufacturing, Gurit has become an expert in the field of "surfacing technology".
Features:
- Proven performance over many years of demanding laboratory testing and blade service
- Light stable
- Available for use with epoxy prepreg and infusion systems
- RAL colour range
- Range of hardener speeds
- Bulk and cartridge (for repairs) supply formats

Bisphenolic gelcoats have the maximum heat and chemical resistance compared to all gelcoat groups. Therefore these gelcoats are widely used in chemical industry where high temperature and chemical resistance is necessary.
Polijel 291 is a bisphenolic based, thixotropic, high reactive gelcoat.
It is used for top level chemical and temperature resistant applications.
The most important feature of gelcoat is not effected many chemicals even at high temperature.
Polijel 291 is used especially production of industrial process equipments, chemical tanks, mould production and for surface coatings againts corrosion.
To obtain the maximum resistance levels avoid using pigment and filler much.

The gelcoats in this group are designed for general industrial applications. They are suitable for economic applications where weathering, water or chemical resistance is not necessary for the products that will be used indoor or paint finish.
Polijel 208 is an orthophtalic based, thixotropic, preaccelerated, general purpose gelcoat.
It's used especially in the production of sanitary equipment, playground equipment and in the automotive industry where the parts will be painted after production. It can also be used in interior decoration and polyester furniture production.
Polijel 208 shouldn't be preferred when aesthetic appearance, water and chemical resistance are needed because it gets matt and yellow in the course of time.

As a leading supplier of composite materials to the wind energy market, Gurit is aware of the quality, performance and longevity issues of composite tooling.
Using knowledge gained over 25 years of composites experience, Gurit has developed a comprehensive range of composite tooling materials designed to be easy-to-use and give exceptional laminate quality and surface finish.
Wet tooling products are suitable for production facilities that specialise in high quality, gel coated parts from a female mould. The products allow customers to achieve a consistent matt finish, with no print-through from the mould surface or backing structure.
These products are offered with a temperature rating of 110, 130 and 160'c and in each case consist of a T-Gel gelcoat which is used in conjunction with a T-Prime or T-Lam resin system.
SPRINT® tooling materials are designed for customers that can cure at high temperatures. From an initial pre-cure at 65°C with an ultimate thermal performance of 160°C.
Features:
- Thermally stable up to 110, 130 or 160°C (320°F) when fully postcured
- Resistant to thermal cycling damage
- T-Gel sag resistant to 0.75mm thickness on vertical surfaces
- Low shrinkage for accurate mould manufacture

These gelcoats are specially designed for mold building applications where impact, heat and chemical (aging effects of release agents) resistance is at high levels. Polijel 220 series are optimized to work with Polipol 320 Resin for mold production.
Polijel 220 is an isophtalic/NPG/special based, acrylic modified, thixotropic, pre-accelerated gelcoat.
It is designed for the production of mould for polyester products.
The most important feature of gelcoat is it's resistance to ageing effects of release agents and styrene.
It has optimal flexibility and advanced stroke resistance.
Refer to our " Poliya GRP Mould Production " bulletin for more information.

With its unique combination of properties, Crystic Gelcoat 14PA has shown that it can overcome one of the most serious problems associated with FRP composite tooling. The phenomenon known as watermarking has the following, unique characteristics: Appears as combinations of gloss and matt areas in patches on the mould surface Gives visible undulations caused by shrink-back, often following the line of brush marks Always transfers to the surface of the moulded component Seen only when the first moulding is taken from the mould

NORPOL® SVG is a family of high-quality gelcoats based on a premium ISO/NPG polyester resin.
APPLICATION
NORPOL® SVG gelcoats are available in both spray and brush versions.
• Recommended peroxide dosage: 1.3 - 2.0%
• Recommended film thickness: 0.55-0.85 mm (wet film)
FEATURES AND BENEFITS:
NORPOL® SVG Gelcoats can provide a significant reduction in emission of volatiles. White spray gelcoat has a VOC content of ca. 30 wt% whilst white brush gelcoat contains only ca. 25 wt%.
The VOC emissions of NORPOL® SVG products are approximately 50 percent lower than those of conventional gelcoats where styrene is the only monomer used.
